Lithium battery solar street lamps use ternary batteries or lithium iron phosphate?

- -

because of using solar energy as solar street lamps, energy saving, environmental protection, easy installation, safe hidden trouble and automatic control maintenance and other characteristics, widely used in the rural road lighting. Solar street lamp has been popular in rural areas, now we all know solar battery into the lithium battery and gel battery, a few years ago due to no special lithium battery technology mature, so people more choice is to use gel battery of solar street light. But with the mature of solar street lamp lithium battery technology, more and more adopted lithium-ion batteries, solar street lamps and the common batteries, lithium-ion batteries on the market is divided into three yuan batteries and lithium iron phosphate, ternary lithium battery solar street lamps used batteries or lithium iron phosphate? That has more advantages? The next solar street lamps factory manager zhu will talk to you guys this question.

a batteries, three yuan

advantage: the performance is less affected by temperature, low temperature resistant, can be used in degrees below zero to degree of low temperature environment.

faults: cycles shorter, relative to the short service life of the lithium iron phosphate. At the same time, poor security and stability, high temperature decomposition, the charges of the electrolyte in the battery and a little on the carbon material, thereby deflagration phenomenon.

advantages: lithium iron phosphate charge-discharge performance outstanding, cycle times, longer service life, high temperature stability, - ℃ will begin to decompose, and in the face of the impact, the situation such as acupuncture, short circuit will not release oxygen, won't produce severe burn, safety performance is high.

faults: performance are greatly influenced by temperature, especially in low temperature environment, the discharge capacity and capacity will be greatly reduced, and its energy density is low.

all in all, three yuan batteries and lithium iron phosphate each have advantages and disadvantages, we not absolutely clear solar street lamp lithium battery which has more advantages. So far, they are not able to tie, ternary lithium battery has the upper hand slightly, but they at least at this stage is not perfect solution. Finally, solar street lamp manufacturers think if it is installed in the northern region, it is recommended to use three yuan batteries, batteries for three yuan stronger resistance to low temperature performance. If it is installed under the south, so the lithium battery solar street lamps use lithium iron phosphate is more cost-effective.
